Embodiment
As shown in Fig. 2 it is the structural representation of the ventilation purifier of low-resistance low-maintenance provided by the invention, it has
The two filtrates volume 1 being oppositely arranged, two filtrate volumes 1 are driven by a motor 3 by crawler belt 4 respectively, in two filtrates
Filtrate 2 is wound between volume 1；
Unlike the prior art, be additionally provided with the limit shaft 5 that two-row spacing is opened, row's limit shaft 5 close to inlet side A,
Another row's limit shaft 5 back and forth detours successively close to air side B, the filtrate 2 between two row's limit shafts 5, forms "the" shape
Winding path, to increase the effective filtration area of filtrate 2, so as to increase processing air quantity and reduce device resistance.
The present invention has two kinds of methods of operation --- normal ventilation cleaning pattern and the generation patterns of filtrate 2, wherein：
In normal ventilation cleaning pattern：Two motors 3 do not rotate, and filtrate 2 does not move.
In the generation patterns of filtrate 2：By being manually set timer timing renewal filtrate 2, or by using pressure difference sensing
Device (is unillustrated), the static pressure difference (i.e. plant running resistance) between the inlet side and air side of filtrate 2 is monitored, when pressure difference reaches
Automatic filtrate 2 is carried out during setting value to update.When filtrate 2 updates, two motors 3 of control order rotate simultaneously, but rotate speed
Degree is different, the 2 linear renewal rate of filtrate measured by controller using counting gear 6 as monitoring and feedback control signal, according to
Range sensor or position sensor (being unillustrated) etc., the radius of two filtrate volume 2 are surveyed in real time, in real time to the rotation of two motors 3
Speed is adjusted, to ensure that the retracting of two filtrates 2 is received, to supply the speed of filtrate 2 consistent.
It should be added that the present invention can according to the air quality control demand of reality, selection using thick effect or
The filtrate 2 of medium air filtration material, but no matter which kind of filtering material is used, using the above-mentioned method of operation of identical.
It is noted that according to use environment, air parameter and the selected specific type characteristic of filtrate 2 are handled not
Together, the different spacing dimension of limit shaft 5 combinations be present, to cause apparatus structure resistance and the resistance of filtrate 2 optimal.
In order to express easily, the distance between adjacent limit shaft 5 of any two in same row is referred to as distance between axles a, claims two
The row spacing b between limit shaft 5 is arranged, in situations where it is preferred, distance between axles a is between 50~600mm, row's spacing b is in 400
Between~700mm, more specifically for example：
(1) using thick effect filtrate material：Distance between axles a is 600mm, and row spacing b is 400mm.
(2) using thick effect (or middle effect) filtrate material：Distance between axles a is 60mm, and row spacing b is 640mm.
(2) using thick effect (or middle effect) filtrate material：Distance between axles a is 50mm, and row spacing b is 500mm.
Referring to again shown in Fig. 3, when using thick effect filtering material, the present invention can also increase automatic ash removing device, its
The deashing suction nozzle 8 being connected including deduster 7 and with deduster 7, the patch of deashing suction nozzle 8 are touched on filtrate 2.
The present invention can be by being manually set timer timing deashing；Also filtrate 2 can be monitored by using differential pressure pickup
Static pressure difference (i.e. plant running resistance) between inlet side and air side, carries out automatic ash removing when the differential reaches a set point.Clearly
When grey, the operation control method of motor 3 is consistent with the generation patterns of filtrate 2, but is intermitten service, often runs once, filtrate 2 move away from
From the length equivalent to deashing suction nozzle 8, then deduster 7 is opened, and deashing suction nozzle 8 is filled by leading screw (being unillustrated) or other transmissions
Put drive to move along the width of filtrate 2, complete one section of deashing of filtrate 2, such do action, be gradually completing with filtrate 2
Deashing.
Referring again to shown in Fig. 4, being another embodiment provided by the invention, it has leading to for two sets above-mentioned low-resistance low-maintenances
Wind purifier (one applies mechanically just effect filtrate, another set of that filtrate is imitated in), the ventilation purification of two sets of above-mentioned low-resistance low-maintenances
The winding path of the filtrate 2 of device is parallel to each other, and using structure provided by the invention, can make the logical of two sets of above-mentioned low-resistance low-maintenances
Interval d of the filtrate 2 of wind purifier in direction of ventilation is purified between 100-200mm with existing two sets of ventilations
The initial effect filtering section of device can greatly shorten compared with being spaced 500-600mm service section easily between medium efficiency filtration section
The design length of ventilation purifier.
It is described above to be merely exemplary for the purpose of the present invention, and it is nonrestrictive, and those of ordinary skill in the art understand,
In the case where not departing from the spirit and scope that claim is limited, can many modifications may be made, change or equivalent, but will all fall
Enter within protection scope of the present invention.
